Windows 10: I bought my computer with Windows 10 installed. No CD. How to find my license?

I bought my computer with Windows 10 installed. No CD. How to find my license?

:)

 

I'm trying to install windows 10 in new computer from USB drive.

I don't really understand what you're saying.

You have two options:

A) Have a previously licensed version of Windows 7 or 8 on a PC, run the GWX upgrade to Windows 10 (which then swaps your Windows 7/8 key to a Windows 10 license), then do a clean install and Microsoft will automatically license that PC provided the motherboard is installed.

B) Have a Windows 10 license, install Windows 10 on the PC as a clean install, and input that license.

Windows 10 upgrade license

The interesting question is that: the upgrade takes place before 29 of July. If I upgrade the PC (change the MB), and I transfer the Win 8.1 license to this new PC (cause 8.1 is retail FPP), will I be able to upgrade to Windows 10 for free? Or a upgrade license must be bought?
